Just upgraded to a C2D MBP, and against my better judgement, I used the Setup Assistant to import my files and apps from my TiBook. One of the oddities I was experiencing on my old machine seemed to follow me. I had been having ".app" show up at the end of any application file in Finder, and the new machine is experiencing this same thing. As an example, it shows "Mail.app", "Safari.app", etc. Anyone know what I can do to fix this?
